The LCD EWP® / Fan Digital Controller has two specific functions. This unique Digital Controller will manage the operation of the EWP® by varying the speed of the pump in response to the coolant temperature and manage control of your electric engine fan.

The Controller has a push-button to lock in any targeted/set temperatures between 40°C (104°F) to 110°C (230°F) . It’s highly recommended you set/target the Controller to closely match your engine’s existing thermostat temperature.

Generally, higher engine temperature will offer improved fuel efficiency and lower engine temperature more power. The Digital Controller will operate the engine’s electric fan automatically once the engine has reached 3°C (5.4°F) above the targeted (set) temperature. Another significant benefit is that the Controller allowsthe EWP® to run on after ignition shutdown to eliminate heat soak.Features Black & White Numerical LCD Screen

THERMAL SWITCHESA Thermal Switch is a device which senses the temperature of the coolant and turns on the electric fan when cooling is needed over a wide range of temperatures. Davies Craig offers two types of switches, a mechianical & electronic version.

MECHANICAL THERMAL SWITCH - PART No: 0400, 0401 & 0404 (12 & 24 VOLT)

The Mechanical Thermal Switch is adjustable from 40° to 100°C (104° to 212°F).It is mounted near the radiator and the stainless steel probe fitted inside the radiator hose making contact with the coolant. The mechanical thermal switch is then connected to the ignition circuit for operation. The thermal switch & relay kit (Part 0404) enables a fan to operate both thermally and also when the air conditioning is running.

ELECTRONIC THERMAL SWITCH - PART No: 0444 (12 & 24V)

Davies, Craig Pty Ltd very own designed Digital Thermatic Fan Switch Kit can be used with our Thermatic Fans, EWP's & competitors Fans. It senses air temperature as it passes through the radiator and has an adjustable temperature range of 40ºC to 110ºC (104ºF to 230ºF). The Temperature Sensor is placed in the radiator fin section as close to the hot coolant inlet as possible so no need to cut hoses.

This switch is operated thermally & also when the air conditioning is in operation.

Simply set the temperature by pressing the set button.

It can run 1 or two fans. The second fan (if applicable) will start 10 seconds after Fan #1 runs.

To convert temperature reading from Centigrade to Fahrenheit, remove the Jumper Pin on the unit next to the LED screen.

DIGITAL GAUGE THERMATIC® FAN / EWP SWITCH KIT

PART #0500 (12 & 24 Volt)

A bright, attractive, compact high visibility 52mm round gauge with LED digital display for mounting in the driver’s compartment!

Automatically activates single or twin fans or a fan and Electric Water Pump at your set / targeted temperature when extra cooling is required. It can also detect transmission fluid temperature.

It senses air temperature as it passes through the radiator with the sensor placed in the radiator fin section or alternatively the sensor can also be placed directly into the coolant system in combination with a Temperature Sensor Adaptor Kit (Part 0409).

Now there is no need to squeeze the probe of the Mechanical Thermal Switch or EWP Controller between the radiator inlet and radiator hose. This simple and economical Adaptor Kit allows easy fitting directly into the radiator hose. Just fit probe into compression fitting, remove about 17mm of radiator hose, fit adaptor between each end of hose, secure hose clamps and the job is done. The kit comes with everything you need for a watertight and effective installation. We even supply rubber sleeves to enable fitment to radiator hose sizes from 32 to 40 mm diameter.

LOW COOLANT LEVEL ALARM KIT - PART No: 1035

The Low Coolant Level Alarm Kit will monitor the coolant level in engines and will immediately identify low coolant should this situation develop. This cool new device comes with a loud audible alarm and will help prevent an over-heating engine and significant engine failure. The unit simply fits into your engine’s top radiator hose and will alert you to the loss of engine system coolant via an audible alarm. This situation may occur when a radiator hose splits or frays, a radiator springs a leak and the engine’s coolant is either low or lost. The vehicle’s simple temperature gauge will not alert the driver to this event and the Low Level Coolant Alarm adds security to assist monitor your engine’s coolant level. Loss of engine coolant can cause the water pump to lose pressure and will quickly develop into to an overheated engine. Most engine temperature protection systems and gauges will not detect coolant loss as they rely on sensing the coolant temperature. When the coolant is lost, the gauges cannot sense engine temperature and as such expensive engine failure may occur.
